Any process with a negative change in enthalpy and a positive change in entropy will be:_______.
harkovskaia [24]

Answer:

a. spontaneous

Explanation:

Hello,

In this case, since the Gibbs free energy is a metric that allows us to know whether a chemical reaction is spontaneous (Gibbs free energy less than 0) or nonspontaneous (Gibbs free energy greater than 0) we can mathematically define it as:

\Delta G=\Delta H-T\Delta S

Thus, if the enthalpy is negative and the entropy is negative, the subtraction become always negative, for which the Gibbs free energy is negative as well, therefore, based on the aforementioned, any process with a negative change in enthalpy and a positive change in entropy will be: a. spontaneous.

Best regards.

Which best describes Rutherford’s model of the atom? fish swimming in an aquarium a sports stadium with a marble at the center a
puteri [66]
Rutherford's model of the atom is also known as the planetary model because this is when he discovered the nucleus of the atom. He also discovered that the nucleus of the atom, located at the center of an atom, is only 1/3000th the size of the atom's diameter. Also, surrounding the nucleus is an electron cloud. Therefore, the best description of his model would be <span>a sports stadium with a marble at the center.</span>
